Decoupling? Before tight monetary policy was used to batter workers and the welfare state into submission, because even with the Euro loose monetary policy would reduce funding constraint. After the near collapse, Cyprus and Greece that is less true.
Additionally the direct approach is much stronger than it used to be. Now either laws are dictated outright (Troika), parallel legislative and judicial systems are built(TTIP), and the whole neoliberal brain rot is being increasingly written into constitutions(debt brakes).
